Dear Ed:

Thank you very much for your May 2 letter and the update on the Marshallese
data. I am glad Charlie asked you to review the SC-57, TG-7 report on
Thyroid Cancer. I felt it didn't cover the Marshallese data adequately and
suggested in my comments that you be contacted.
I noted that your table lists six total thyroid cancer whereas TG-7 report

gives seven.

Also, I think seven was the number in Bob Conard's report and

the number also appears in the UNSCEAR report. I assume this difference of
one is the Utrik case you mentioned in your note to Charlie.
I probably told you that in our meeting at Majuro in December, the
Marshallese expressed their belief that they are experiencing a great
excess of thyroid cancer as well as birth defects. I don't know how these
erroneous perceptions can ever be corrected.
Thank you again for your letter.
With best regards,

W. Gu Ph.D.
